• Arizona statewide default escort-by-dimension rule (A.A.C. R17-6-401/402/404): over 11 to 14 ft wide = REAR escort; over 14 to 16 ft wide = FRONT AND REAR escort; over 15 ft high = FRONT escort with a height pole. Overhang (R17-6-307): front overhang over 20 ft = front escort; rear overhang over 20 ft = rear escort; both = front and rear. No width-only 'front escort' tier exists (front escort by width triggered only within the front+rear pair at over 14 ft). Law-enforcement escorts required where R17-6-412 Table 4 specifies, or at Department discretion (R17-6-306); DPS must be contacted at least 12 hours before transport. Route-specific Table 4 rules frequently require escorts at LOWER widths than the statewide default, so the actual requirement is the greater of the statewide rule and any Table 4 route rule. Over 16 ft wide or high moves into Class C special-permit territory. Not weight-tied.
• Loads within the continuous-travel envelope (<=10 ft wide, <=14'6" high, <=120 ft long, <=250,000 lbs, overhangs <=10 ft) may travel continuously incl. nights/weekends (R17-6-401.A). Loads EXCEEDING 10 ft width or 14'6" height must move DAYLIGHT ONLY (R17-6-401.B) unless granted night/weekend transport. Night & weekend transport (R17-6-402) allowed for loads over 10 to 16 ft wide or over 14'6" to 16 ft high on Department-authorized Table 4 routes on any non-holiday night/weekend, from no earlier than 3:00 a.m. until one-half hour after sunset. Metro curfews (Phoenix, Tucson, Yuma) apply Mon-Fri 7:00-9:00 a.m. and 4:00-6:00 p.m. on listed routes.
• New Year's Day, Memorial Day, Independence Day, Labor Day, Thanksgiving Day, Christmas Day.
